Thomas Willoughby has a helpful piece entitled “Does Leviticus 18 Apply to New Testament Believers?” In particular, he seeks to answer a common argument that the prohibition against homosexuality in Lev 18:22 no longer applies under the new covenant.
Willoughby models a clear and effective use of the context and structure of the text to conclude that not only Lev 18:22 but the chapter’s entire sexual ethic has abiding significance. I might quibble with some of his secondary conclusions, but overall, he makes a good case from both the context and correlation with the rest of Scripture.
